You need to ask DiAVC about it. I have confirmed that DGSource() itself is threadsafe. I can open a script several times in simultaneous VirtualDub instances and they play fine and independently. Beyond that, it's your problem to get MT working. I know nothing about it, and more precisely, I don't c...

That's all I can do for you on this issue. Use your first script.

I've found some code that makes DGSource() not thread-safe, and therefore not compatible with MT. I have corrected it and slipstreamed it into build 2025. So redownload build 2025 and update DGAVCDecodeDI.dll. Please test it and report your results.

Just use DGSource() and enable multithreading in the DiAVC configuration.

As I said, do not attempt to MT the DGSource() filter. Use DiAVC's integral multithreading.

DGSource() code itself is thread-safe. It's the combination with DiAVC that causes the issue, I believe.

I believe you have to not attempt to multithread the source filter but only the remaining part of the script. I know that DiAVC is multithreaded and I see it using multiple threads on my PC. So perhaps you have it misconfigured. Please consult DIAVC for assistance in that regard.

I don't know anything about MT and have no interest in installing it.

Didée is our local expert on this. He has performed similar experiments for DGDecNV. Maybe you'd like to ping him about this.

All new builds will be listed in this thread as they are released. Please do not post problems or questions in this thread (they will be deleted). Start a new thread in the DGAVCDecDI forum.

Build 2025 is now available.

I have revised the parsing to allow for profile 244 and I now have your stream playing fine without crashing. I will release a new revision this evening if my regression testing goes without surprises.

Sorry but MPEG2Source() requires an index.

You're not disturbing me; I appreciate you bringing this issue to light.

Looking closer at the spec, I see I have to parse the SPS differently when profile=244, so I am probably reading the wrong frame_num value. I will continue investigating.

It has the same problem with illegal frame_num value.

What are you using to encode this? Is it an official version of x264.exe? If so, you could ask the x264 guys about it.

Please make a small clean raw 264 file in lossless mode. I can't believe that x264 will produce IDR slices with frame_num not equal to 0.

I don't know how that is happening, unless some uninited variables are taking on very lucky values for you. Anyway, I demuxed the 264 out of the MKV and ran a parser on it. I get the dump below. You can see that the first IDR slice has a frame_num of 1 (must be 0 by spec). This is ILLEGAL and so you...

Even if your soft can't process such files properly at the moment, why you don't want to add this feature? Why you don't want to investigate this issue in details? I do not understand. Really. I never said I would not support it. I said this quite clearly: "If DiAVC supports these lossless files I ...

Open the Help/About box in DGAVCDecDI. It should show version 2024. Is that what you have? If so, there is no way you can play that file.

DGAvcDecDI 2001 crashes when playing file specified in URL below. I am using trial version of last DiAVC decoder (1.2.2). http://rationalqm.us/board/viewtopic.php?f=8&t=69 I do following: 1. Load file to application 2. Play it (it plays correctly). You've lost me already. DGAVCDecDI cannot play the...

The file does not crash for me. It just shows garbage.

CUVID is the programming interface for using the Nvidia video decoding engine on the GPU.

My understanding is that CUVID does not support lossless x264 streams. Unless, you can show otherwise, there's nothing I can do about this.

The file won't play in VLC, so I am not interested in looking at it.

What does "loseless" mean in the file title?

Sorry, but I don't speak Russian and can't figure out how to download it. Can you use mediafire.com, please?

It seems there is an incomplete slice at the end of the file.

As it is a small change for a rare issue, I have slipstreamed a fix into 2037. Please re-download and update DGIndexNV.exe.

I've duplicated it. Investigating...
